Because the soil didn't have the same nutrients it has now due to lack of decomposition of other plants and animals.
The answer is A: 'The central vacuoles contain little water'. Wilting occurs due to a plant losing more water than it can absorb through its roots from the ground. Wilting results in a loss of turgor pressure<span> to almost zero.Typically, wilting occurs during very low soil moisture conditions. However, wilting can also occur under extreme cold conditions and in very saline soil.</span>
Nucleic acids are composed of nucleotides. These nucleotides are in themselves made by nucleosides (purines and pyrimidines) bound to one, two, or three phosphate groups. Thus, the answer is D.
Ions would require a gas to remove electrons
Energy is when bonds are broken
Carbon doesn't comprise of water
Polymers are comprised of Carbon and Hydrogen, among other things, so that would he the correct answer
